Explanation of Control
System
Safety System
Electromagnetic Flame Failure Gas Valve
The purpose of the safety system is to shut off
the flow of gas if the pilot flame goes out. It is
comprised of the flame itself, the thermocouple,
and the flame failure gas valve.
The purpose of the safety valve is to shut off the
flow of gas if the pilot flame goes out.
Inside the body of the gas valve is an
electromagnet connected to a spring loaded
plunger. When the electromagnet is energized, it
holds the plunger in, allowing gas to flow through
the valve.
When the electromagnet is
de-energized, the plunger snaps to the closed
position, stopping the flow of gas.
The pilot flame is lit by holding in the gas
control knob, which in turn temporarily pushes
the plunger inside the safety valve open and
allows gas to flow through. Once the burner is
lit, the thermocouple will begin to generate
millivolts (after about 10 to 30 seconds of being
heated) and will energize the electromagnet
inside the gas valve.
Once energized the
electromagnet holds the plunger inside the gas
valve in the open position. The plunger has to
have been pushed all the way in for the
electromagnet to be able to hold it in place. If
the burner flame goes out for some reason, the
thermocouple will cool after about 10 to 30
seconds and stop generating millivolts. The
electromagnet will then de-energize, and the
plunger will snap shut, cutting off the flow of gas.

Tip
Millivolts are provided to the electromagnet by
the thermocouple (not shown) which generates
millivolts when heated. The thermocouple screws
into a fitting at the back of the gas valve to make
an electric connection. By pressing in the gas
control knob, the plunger can be temporarily held
open while lighting. There's two reasons for this;
gas has to flow through the safety valve to make
it possible to light the pilot burner, and secondly
the plunger has to be pushed all the way in for
the electromagnet to hold it in.
I.e.; the
electromagnet is strong enough to hold the
plunger in once there, but is not strong enough
to pull it in by itself. Sometimes a problem with
the flame not staying lit after releasing the button
can be attributed to not pushing the plunger all
the way in.
Figure 3.2a
The tip of the thermocouple is located in the pilot
burner flame, and the nut at the other end of the
thermocouple screws into the back of the gas
valve. Inside the copper tubing is a wire which is
joined at the tip but insulated from the rest of the
tubing. These two parts (the copper tubing and
wire) make up the "wiring" for an electrical
circuit. When these two dissimilar metals, wire
and tip, are heated an electrical voltage is
produced. This type of thermocouple generates
between 7 and 30 millivolts when heated in the
pilot flame.

Cleaning / Maintenance
CAUTION:
Always turn off the gas supply before cleaning.
This unit is not water proof.
Do not use water jet spray to clean interior or exterior of this appliance.
Routine Maintenance
To achieve the best results cleaning must be regular and thorough and all controls and mechanical
parts checked and adjusted periodically by a competent serviceman. If any small faults occur, have
them attended to promptly. Don't wait until they cause a complete breakdown. It is recommended
that the appliance is serviced every 6 months.
Clean the griddle regularly. A clean appliance looks better, will last longer and will perform better.
Carbonised grease on the surface or on the griddle plate will hinder the transfer of heat from the
cooking surface to the food. This will result in loss of cooking efficiency.
NOTE: Each griddle is supplied with a scraper tool and a pack of blades for cleaning the griddle
surface. Griddles with both ribbed and flat surfaces are supplied with two scraper tools and
two packs of blades for use with both flat and ribbed surfaces. These are for use with both
chromed and steel surfaced griddles. NEVER use the ribbed scraper blade on the flat
chrome surfaced griddle plate.
WARNING
THE BLADES FITTED TO THE
SCRAPER TOOL ARE EXTREMELY SHARP AND ARE TO BE USED WITH CARE.
DO NOT use water on the griddle plate while this item is still hot as warping and
cracking may occur. Allow the griddle plate to cool down before cleaning.
NOTE:
• DO NOT use abrasive detergents, strong solvents or caustic detergents as they could corrode or damage the range.
• In order to prevent the forming of rust on the griddle plate (Steel Plate), ensure that any
detergent or cleaning material has been completely removed after each cleaning. The appliance should be switched on briefly to ensure the griddle plate becomes dry. Oil or
grease should be spread over the griddle surface in order to form a thin protective greasy
film.
To keep your griddle clean and operating at peak efficiency, follow the procedures shown below:After Each Use
1.
Clean the griddle with the supplied scraper tools to remove any food debris.
C AUTI ON
Always ensure that an even pressure is applied over the whole surface of the
scraper tool when using on the flat chromed surface of the griddle, to prevent
scoring of the surface.
NEVER bang the sharp edge of the scraper tool on the flat chromed surface of
the griddle as this will damage the chrome finish and invalidate the warranty.
2.
Always ensure that the scraper tool blades are changed regularly to ensure that the scraper tool
works efficiently and prevents damage to the griddle plate surface.

Piezo ignitor not sparking
Short in high tension lead
If repeated sparking of the piezo shows
intermittent sparking at the electrode, then the
lead should be traced to find area of short. This
can normally be visually seen as the spark arcs.
If the lead is shorting the best solution is to
replace it, as the electrical insulation strength of
the lead may have deteriorated.
Pilot flame too small
If pilot can be lit but the flame is too small to impinge on the thermocouple, then check the gas
pressure. If ok, remove pilot injector from pilot
burner and check for blockages and/or correct
size.
If the spark arc can be seen at the electrode
insulator at the pilot burner instead of at the
electrode tip, then the insulator probably has a
fracture and should be replaced.
Thermocouple faulty
Inspect thermocouple for build-up of carbon or
food deposits on the tip. Clean off any deposits,
taking care not to scratch off the aluminium
coating on the thermocouple.
Piezo ignitor faulty
If no spark at all can be generated, remove piezo
ignitor and hold close to the hob body, depress
piezo ignitor and if a spark cannot be generated
to hob body the piezo ignitor is faulty and should
be replaced.
Check that the thermocouple tip is in the flame
zone of the pilot burner. When the burner is lit,
the flame should impinge on the top 5mm of the
thermocouple tip.
NOTE: The thermocouple should not touch the
burner.
Check
thermocouple
connection
to
gas
control is firm (loose connections will cause resistance in millivolt circuit and result in pilot outage).
If connection is OK, then disconnect the
thermocouple from the gas control, light the pilot,
and whilst holding the control knob in, measure
voltage between the thermocouple internal wire
(refer figure 5.2.1) and earth (e.g. the body of
the gas control). This should read approximately
30mV. If this reading is less than 10mV then the
thermocouple is faulty—replace.
Tip
Internal Wire
Figure 5.2.1
Gas magnet faulty
If thermocouple milli-voltage is above 10mV, and
the pilot still will not hold, then the gas magnet is
faulty - replace.
NOTE: Oven valves will require replacement if
the gas magnet is faulty.
